摘要
塔里木盆地HD油田薄砂岩油藏为2层产油层,属于超深、超薄的中低渗层状边水油藏,采用双台阶水平井注水开发。利用相渗曲线,建立该特殊油藏水平井采液(油)指数、吸水指数随含水变化的经验公式,经现场生产及测试资料验证,符合程度较高,对预测该油藏水平井注采能力、合理调整注采关系、提高水驱采收率具有重要指导作用。
The thin-sandstone reservoir of HD oilfield in Tarim basin is characterized by dual payzones, ultra-deep and ultrathin laminar reservoir with medium-low permeability and edge water. It is developed by water injection technology of double-step horizontal wells. This paper gives the empirical formulas for horizontal well＇s fluid productivity index and injectivity index changing with water cut applying the relative permeability curves. The case study indicates that these formulas are practicable for prediction of injection-production capacity, rational regulation of injection-production strategy and EOR by horizontal well water flooding in this reservoir.
